Not to be pedantic, but the G50/50 was only for the 1989 930, so made for one year. The 91 and up 964 Turbos had a G50/52, which had the same ratios as the G50/50, but i'm led to believe the 50/50 is stronger? Not sure why, or even whether that is true? But in most respects the 50/50 and 50/52 are the same.
